The new electrified Brompton has a neatly integrated front battery pack and charging port, that can be carried separately as a small bag when not in use.
Maintaining the "iconic style and craftsmanship of the Brompton folding bike", it's a similar size and weight as the non-electric version but with a 300Wh, 2.8kg battery added, allowing for a range of between 25-50 miles depending on the level of assistance used. The bike itself is fairly light, weighing 13.4kg in total.
There are three assistance levels from the 250W front hub motor, and Brompton say the bike runs very smooth manually too so you can save the power for when you need it most. There's even a torque and cadence sensor included. Brompton teamed up with Williams Advanced Engineering to develop a motor that would integrate well with a folding bike, and Brompton say the end product is their most technically advanced bike to date.
The battery/bag idea looks particularly interesting, clipping neatly onto the front and becoming a compact bag off the bike with a shoulder strap for easy portability. What's more, your ride settings can all be customised via Brompton's app, where you can also log mileage and service history.
The bike still folds as neatly as a non-electric Brompton
The e-Brompton (as we've just named it) will be available with either two or six-speed gearing, with prices starting at £2,595. They won't ship out until early 2018, but you can already reserve one with a £200 deposit on Brompton's website.
If you were at Ride London this weekend you may have already got a demo - but Brompton are also offering demos at their Brompton London Junction shop throughout August, plus at numerous events around the UK. Check out brompton.com/electric for more info.
